Mapping fields in modules
Remap source and target fields to the same interface fields to keep connections stable as databases evolve
Field mapping lets module consumers connect a target database to a module and align incoming interface fields with existing fields in their target database. It also supports remapping later, so connections remain usable even when the source or target schema changes.
Mapping fields helps you:
- Reconnect databases more easily when a connection was removed or needs to be re-established.
- Use a module as a standalone app or combine it with other modules in the same workspace.
- Change fields in the source database (within the same table) while keeping the interface fields stable.
- Change fields in the target database (within the same table) while keeping the interface fields stable.
Field mapping is based on the interface contract: interface fields stay stable through their IDs and public names, while source and target fields can be realigned over time.
